AutoCAD Civil 3D

[#1]

i've got a pretty long corridor and usually when i open the drawing i have to reattach some of the targets alignments and profiles to get the sections looking correct. pita. is there a way to lock the targets or do i just have to be diligent in reasigning the targets? c3d2012. thanks.

Are the targets Dref'ed alignments/profiles? What service pack, if any, do you have installed?

[#3]

the centerline alignment & profile are dref'd but all the others like eop and ditch are in the drawing. service pack 2?

So, was this a case of Civil 3D objects being locked as described in this Being Civil blog?  http://bit.ly/Uo9tLv
